To all whom/ it may concern.:

Be it known that I, HORACE L. ARNOLD, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Recorders, of which the following is a specification.

This invention relates to recorders or registers adapted for use with vehicles of various constructions, but particularly adapted for m echanically-propelled vehicles-snch as automobiles, street-railway cars, dac-although it can be effectively used in connection with horse-drawn vehicles, the present improvement being designed to furnish a record of the time of starting, the rate of progress, and the time of stopping of the vehicle, together with a record of the sounding of an alarm, such as a bell or other warning-signal; and one object of the invention is to provide an improved instrument which will record certain events and the time of their occurrence in plain printed characters, so as to be easily and quickly read by those not possessed of special technical training.

A further object of the invention is to provide a recorder comprising an improved timepiece-act uated record-sheet provided with separate time-spaces denoting similar periods of ti me duration and an improved event or performance impression producing` mechanism actuated on the occurrence of the event to print on the record-sheet in the particular space corresponding to the time in which the event occurred a mark, symbol, or character indicating the occurrence of such event.

A further object of the invention is to provide a recorder comprising record-sheet mechanism comprehending a timepiece and a record-sheet actuated thereby and provided with separate time-spaces denoting similar periods of time duration, an event or performance impression producing mechanism actuated on the occurrence of the event to print on the record-sheet in the particular space corresponding to the time in which the event occurred a mark, symbol, orcharacter indicating the occurrence of such event, means operative to shift one of said mechanisms laterally or transversely of the other, thereby to obtainA the printing of such marks, symbols, or characters in lateral paths on the recordsheet, and means for returning the shifted mechanism to its starting position.

A further object of the invention is to provide a recorder comprising a ti mepiece-actuated drum carrying a record-sheet and an improved speed-recording mechanism organized for connection with a moving or rotary part of a vehicle and operative to produce a record of the rate of progress of such vehicle.

A further object of the invention is to provide a recorder comprising a timepiece-actuated drum carrying a record-sheet and an improved alarm-recording mechanism organized for connection with an alarm or other warning-signal and operative to produce a record of the use of such warning-signal or alarm.

A further object of the invention is to provide a recorder with a number of improved features embodying, among others, an improved record-sheet mechanism, an im proved speed-recording mechanism effective to accurately record the speed of a vehicle,together with the time of starting and stoppage thereof, an alarm or warningsignal recording mechanism, and trip-indicating mechanism, each of which mechanisms also embodies various novel features.

Figs. 29 and 3U are detail views of the drum-holding means, and Fig. 31 is a det-ail of the bell-crank carrying the alarmrecording devices.

Similar characters of reference indicate corresponding parts in the different iigures of the drawings.

The object of the invention, as above set forth, is to produce a record of events and the time of their occurrence in plain prin ted characters, so as to be easily read by persons not possessed of special technical training.

There are now in use various speed-recorders in which a pen. or analogous instrument is used to make a waved line on paper secured to a drum rotating at a uniform time rate. While said record Amay be accurate, it, however, cannot be read at sight, but must be measured and interpreted by a person having special knowledge of this form of diagram.

1n the present improvement an entirely different method is pursued, with the result of producing a plainly-printed record-sheet accurately exhibiting the occurrence of one or more events, the mechanism being adapted to record the occurrence and frequency of various events upon a single record sheet or card, the present mechanism, however, being Fig. 2S is amore especially constructed for the production of a record of the time of starting, rate of progress, and time of stopping a vehicle of any description, while at the same time keeping a correct record of the sounding of an alarm, such as a bell or other warning-signal, as well as indicating the number of miles traveled by the vehicle. The means employed for producing this record comprise a record sheet or card which is appropriately inscribed on its face before placingin the machine and further im printed during the progress of the vehicle by a plurality of printing mechanisms shown herein, independent of each other, one for each series of events which are to be recorded. The record-sheet is in operative connection with and is actuated by a timepiece or time mechanism and is moved at a uniform rate of speed thereby.

rlhe printing mechanisms, which record the occurrence of events by making impressions on the record-sheet, are actuated on the occurrence of the events themselves and hence produce their record on the sheet in times of their own entirely independent ol" the uniform travel of thel record-sheet and by their varied location of such impressions on the sheet and by the variation of the intervals separating the impressions thus made 011 thc sheet give an accurate record of the rate of progress of the vehicle and the sounding of the alarm or other signal.

In the case of many vehicles-as, for instance, an automobile or a street or other railway car-there are two wholly different series of events to be recorded-first, the starting of the vehicle, its rate of progress so long as it continues to advance, and its stoppages, and, second, the sounding of the alarm. It is of the greatest importance to the manager of a street-railway line that he should be able to know certainly the time of the beginning and ending of each trip of his cars and also the rates of speed at which such cars are run, it being also in case of accident of very great importance to have an indisputable record of the alarm as well as the velocity of the vehicle at the time ot' the occurrence of the accident. Hence in the present improvement two entirely independent sets of record-printing mechanisms are employedthe one actuated by a rotary part or wheel of the vehicle and the other actuated on the sounding of the alarm-each producing a record on the recordsheet in a proper time division thereof, so that a plainly-printed record is produced, which can be easily and quickly read by any person of ordinary intelligence, whereby it is capable of being used as indisputable evidence in court or to persons without special technical training.

The rate of vehicle progress is always a matter of uncertainty when judged by the eye only, and an accurate mechanically-produced record of the vehicle speed is of the utmost importance in case of accident and is also of great significance to managers of street-rail- IOO IIO

way cars, who wish as nearly as possible a uniform rate of speed to be maintained, and they are therefore especially interested in the Work of each motorman, since he may from motives of his own run at very low rates of speed during certain portions of his routes and at much higher rates than the rules ofthe road permit over other portions thereof. It is also very desirable that the rate of speed at which hired vehicles have been driven should be certainly known to the owners, as well as the total distance traveled and other particulars, which can be readily ascertained by the use of the present improvement.

This improved recorder in the form shown and which may be its preferred t'orm, if desired, includes improved record-sheet means or mechanism embodying a record-sheet and a timepiece or time mechanism for shitting said record-sheet, improved speed-recording means or mechanism, and improved alarmrecordingmeans or mechanism. In the presentinstance, also, the recorder embodies in connection with the alarm-recording mechanism a trip-recording means or mechanism to indicate the particular trip during which the alarm is sounded.

Since it is desired when the recorder is used in connection with road-vehicles, such as automobiles, to know the distance which the vehicle has traveled, the recorder may in the form shown embody, in combination with its other recording` mechanisms, a cyclometer of any desired or preferred construction.

Various forms of record-sheet may be used in practice upon which the record ot' the occurrence of the various events may be imprinted, and while it is of course desired that a recording-machine should be as small as possible it is nevertheless absolutely necessary, if the machine is to furnish a record of value as evidence in a court of law, that there should be space enough given upon the sheet so that the records can be easily read and accurately scaled.

The record-sheet length of travel for a given period of time-say an hour-determines the frequency with which.the speed of the vehicle may be recorded, or, in other words, the smallness of the travel unit of record which may be adopted, the greater the movement of a record-sheet in a given time, however, the

less the total time that can be covered by a` single record-sheet ot given dimensions. In the present instance the record-surface of the sheet or card is shown as twelve inches in length and three inches in width, so that a record-surface of about twelve inches long and three inches wide may be obtained.

ln practice the record-sheet 2 may have its time divisions printed in red on thin strong paper and have at one end a gummed Hap 3 (see Figs. 26 and 27) projecting beyond the end of the sheet, such sheet being provided with three holes 4, 4', ande", located one near each edge at one side of the sheet and a third located near one edge at the other side of the sheet. ln the form of sheet shown it is given twenty-tour lengthwise spaces 5, formed by lengthwiselines 5', which are shown inclined, so that when the sheet is placed on its carrying-drum these lengthwise spaces will form a continuous helical path 5" around the drum, and in which helical path the event-records are printed or recorded. The sheet is also provided with crosswise time divisions 6, separated by distances determined by the time occupied by one rotation of the drum.

If the record-sheet is to constitute a seven days record of twelve hours each, a sheet would be ruled with sufficient heavy crosswise lines to form twelve spaces at equal distances apart, each representing one hour of time, and each of which crosswise spaces would be again divided into a series of twenty-four smaller spaces, each representing two and one-halt' minutes of time. The tirst lengthwise space on the sheet would be printed, for instance, Sunday, March 5,1899, A. M., the next lengthwise space being marked simply 1). M. for the same day, the third lengthwise space being marked Monday, March 6, 1899, A. M., the next lengthwise space being simply marked P M. for the same day, and then in the succeeding spaces, in the manner just indicated, Tuesday, Vednesday, Thursday, Friday,7 and SaturdayA..M.andP.M..7 thuscompleting the week of time on the record-sheet. The sheet. being twelve inches in length and its carrying-drum making one turn in twelve hours would give, of course, one inch of travel for each hour ot time and one-twelfth ol an inch for each five minutes of time and one twenty-fourth of an inch for each two and one-half minutes of time. This precludes the possibility of a legible record ol' much smaller travel units than aquarter ot' a miie of Vehicle progress at a twelve-mile speed. rlhe space therefore available for the milcrecord is one-twelfth of an inch, and if this record is made in one-quarter-mile divisions the impressions made upon the sheet would only be one forty-eighth ot' an inch apart, and at a twenty-four-mile speed per heur the quarter-mile impressions would be only one ninety-sixth part ot an inch from each other, which is as close or closer than can be distinctly read, even with the best of recordprinting.

It is desirable that the speed-record impressions recording the progress ot' the vehicle should represent as short travel units as possible, anda record made once in a quarter of a mile while it would be sufficiently close to satisfy the requirements of the vehicledriver on ordinary occasions would not besufiiciently close to be ot' particular value in case of accident. 'lhe weekly sheet or card just described has certain points of convenience and advantage, and it could readily be furnished in blocks ol titty-two cards giving the entire year ot' time printed with daily IIO dates all ready for use; but it is extremely desirable that a much smaller division of a mile than quarters should be made. This can only be done by giving more length of record-space per time unit, and therefore the improved sheet 2 shown in the drawings, to the use of which the mechanism herein illustrated is adapted, is provided, as above set forth, and which is about twelve inches in length and about three inches in width and is provided with twenty-four lengthwise spaces 5, formed by inclined lengthwise lines 5', forming when the sheet is placed on its earrying-drum a helical path.

In the present instance the mile-printing Wheel (see Fig. 20) carries thirty-two printing-faces, shown herein as lines, as hereinafter more fully described, which provides for twelve miles an hour, the drum making a complete rotation in this time by means of the time mechanism, and the record-sheet providing one inch of record-space for the mile, the marking of the one thirty-second of a mile speed in divisions one thirty-second of an inch apart, so that at a speed of twentyfour miles an hour the record-lines would be one sixty-fourth of an inch apart, legible and easily measured.

In practice the upper left-hand part of the first lengthwise division 5 of the sheet would not receive any portion of the event-record from the printing mechanism, and this part of the sheet may be graduated as shown and could be sheared oif from the sheet without mutilating the record to enable the slip so sheared oftl to be used to scale the printed record made on the sheet, as will be readily understood.

In practice the card may be printed as indicated, so that when applied to its carryingdrinn the top division, at the right-hand corner thereof, would read Noon, while the middle division at the left would read Midnight,the bottom division reading Noon again, the intermediate times being marked in heavy Vert-ical line divisions 6, covering fifteen minutes time on the card, with lighter intermediate vertical lines 7, forming fiveminute spaces 7 on the card, so that the time of all records made on the card can be noted at a glance, thus avoiding all uncertainty as to correct reading.

In practice the card may be printed in a color different from that made by the recording mechanism-as, for instance, printed in red, as above stated-while the speed-recording mechanism could produce its record in black or of any other suitable color, while the alarm-recording mechanism could produce its record in blue or any other suitable color.

To place the sheet on the drum, hereinafter described, the gummed flap 3 is first Incistened, and then the pin-holes et and 4 at this gummed end are placed on separate pins or projections 9, carried by the drum, (see FiO. 21,) the opposite end of the card being then crates passed around the drum until such ends meet, the pin-hole e therein registering with one of said pins 9, whereupon the free end of such sheet is pressed down on the moistened iiap, which thereby retains it, and thus secures the same to the drinn. The drum 10 is, as above stated, moved at a uniform rate of speed by suitable time mechanism 12, which time mechanism may in practice constitute any ordinary clock-movement, (see Fig. 9,) not necessary to be herein more particularly described, and of such size as to permit the desired size of drum, which for the twelveinch record-sheet would be about three and thirteen-sixteenths inches in diameter, to rotate freely upon the clock-case or other guiding means with which the clock mechanism would be furnished. In the present instance the drum rotates upon the clock-case 13, (see Fig. 9,) lixedly secured to a part, as the rear wall b,of the recorder ease or casing A,adapted t0 inclose the operating mechanisms. The work which this clock mechanism performs will not in any way interfere with its timekeeping performance, and consequently the dial 14 thereof may be in a position to be read either from the interior of a car when the recorder is used in connection with a street-rail-` way car or by a motor-driver or passenger when used in connection with a motor-vehicle, and for this purpose the recorder case or casing A is provided witha glass-dial door 15, properly cased at its edges, and which door is shown hinged to the recorder-casing, so as to permit the door to be opened upwardly, one leaf of the hinge being provided with a projection 16, (see particularly Figs. 1, 2, and 14,) extending through a slot 17 in the casing-Wall to cooperate with a locking-bolt, hereinafter described. Since in the present instance this drum rotates once an hour, it can be driven directly from the minute-hand shaft or post 1S of the clock, it being connected therewith in some suitable manner. In the present instance this drum 10, of a width adapted to properly carry a full-width record-sheet and provided with pins or projections 9 on its periphery for the holes 4c, e', and 4 of the record-sheet, is furnished atits front edge with meanssuch, for instance, as a plurality of arms 19-preferably connected at their inner ends by a 1eb 20, having an opening 21, shown herein as angular, for the reception of the minute-hand post or shaft 18, which for this purpose is provided with an angular end 155/, projecting beyond the minute-hand. It will be readily seen that the arms 19 may be connected to form a continuous head or web for the drum, if desired, and as this is an obvious equivalent to said arms such a construction is within the scope of the claims.

For positively maintaining the drum in operative connection with the minute-hand post and against movement thereon and to permit the same tofbe readily and quickly removed therefrom suitable mcans is provided,

IOO

IIO

which in the present instance comprises a pair of spring-held members or clips 22, (sec Fig. 21,) each of which is shown pivotally secured to one of the drum-arms and also shiftably connected with another of said arms by means of a pin 23 and slot 24, the slot in the present instance being formed in the clip, while the pin projects from the arm. Each clip is shown forked or bifurcated, whereby it incloses three sides of the angular end of the minute-hand shaft, one part of such clip being adapted to project into a groove or slot 25, formed in such angular end, and held in such position by a spring 26, having one end secured to said clip and its opposite end to the companion clip. (See particularly Figs. l, 9, and 2l.) Each of the clips is provided with a finger or thu mb piece 27, whereby when it is desirable to remove the drum from the shaft this can be readily accomplished by merely drawing the finger-pieces toward each other, whereupon each clip will be swung on Vits'pivot, so as to throw that part thereof which is in the groove or recess of the shaft free therefrom and against the action of its spring, whereby the drum'may be readily removed from the shaft, the clips being limited in their swinging movement bythe combined slot-and-pin connection above referred to. By means of these spring-clips it will be seen that the movement of the drum longitudinally of the shaft is positively prevented.

To insure the placing of the drum in the correct position each time on thehaud-shaft, the web of the arms istshown provided with aprojection or teat 20, adapted to engage a recess or groove 28, (see particularly Figs. l and 21,) formed in such post, whereby in order to permit the placing of the drum ou the post such projection or teat 20 must register with the groove 28 in the shaft. nipulation of this double spring-clip by means of the finger-pieces the drum can be completely and instantly released from the clock mechanism and can be readily withdrawn from the recorder-case to permit the removal ofthe old record-sheet, which is accomplished by cutting at the line where the ends meet, whereupon a fresh record-sheet can be quickly and readily applied, after which the recorddrum may be slipped back in place on the clock-case, whereupon the double spring-clip will automatically operate to secure the drum to the minute-hand post or shaft.

lt is not necessary that the record-sheet should be changed on the drum at any specified time, since all that is necessary to secure another record for twenty-four hours ou the sheet is to inscribe the sheet with the number of the day of the month in pencil at the time division of the sheet indicated by the clock when the new sheet is placed in the recorder, and since the drum can have but one position relatively to the min nte-hand post. owing to the teat or projection 20' audits registering groove 28, it follows that no matter what time the new card is placed in thc re- On the maeerder it will always carry a full twenty-four hours record. lf the card is applied at twelve oclock noon it willcarry a record until twelve oclock noon the next day, which will fill the card. By dating the card in pencil at the hour of its application the day upon which the record is made is thereby defined. To produce upon this card a record of the event which is to be recorded, suitable recording mechanism is provided. This recording mechanism in the form shown comprises two independent mechanisms, one for recording the speed of the vehicle and also the starting and stoppage thereof and the other for recording the use or operation of a warning signal or alarm, and in the present case the former will be designated as speed-recording mechanism, while the latter will be designated as alarm-recording mechanism, and while each may be entirely separate and distinct from the other not only in construction, but also as to the means for operating it, in the present instance, however, these independent recording` mechanisms may be operated transversely of the record-sheet by the same means, and therefore the speed-recording mechanism has its supporting parts constructed to facilitate this organization. In the form shown (which may be its preferred form, if desired) the speed-recording mechanism (see Figs. 3, it, 5, 1l, and l2) comprises impression or print-ing mechanism and actuating mechanism. The impression mechanism in thel present instance is carried by a suitable bracket or arm 30, with which such impression mechanism maybe readily assembled before the bracket or arm is placed in the recorder-casing, whereby the assemblage of the parts is facilitated. This arm or bracket 30, which in practice may be a casting, is mounted for vibratory or oscillatory movement on a suitable rock-shaft 3l, journaled in suitable uprights or supports 32 and 32', located one adjacent to the front wall a and the other adjacent to the rear wall b of the casing. When the impression mechanism is assembled for movement laterally or transversely of the record-sheet, it is necessary that this bracket and its rockshaft be so constructed that on the actuation of the shaft the bracket will be vibrated, while at the same time such bracket may be shifted longitudinally of such shaft, and for this purpose the shaft is shown as a squared shaft, while the bracket is provided with a sleeve 30@ having a squared socket, whereby the operation of the parts iu the manner indicated is obtained. The impression mechanism comprises a suitable printing device, shown and designated herein as a mile-printing wheel 33, since one complete rotation thereof is equivalent to a mile of vehicle travel, and which in practice will be formed of hard steel and of any desired width. This wheel in the form shown (see Fig. 20) will be provided, as hereinbefore set forth, with thirty-two printing surfaces or teeth 34, of

IOO

IIO

different lengths-that is to say, the lengths 0f the teeth crosswise of the wheel will be graduated in the usual manner of a grad uation of thirty-two parts to a unit-and one of these teeth, as 35, will be slightly wider or thicker in cross-section than its companion teeth, whereby it will indicate the termination and commencement of each mile un mistakably. This printing-wheel 33 is carried by the vibratory bracket or arm, and for this purpose the arm is shown bifurcated at its forward end, intermediate the members 36 and 37 of which the mile-printing` wheel is journaled. An ink-supply device-such, for instance, as a felt roller SS-is located in position to supply the mile-printing wheel 33 with ink, and in the structure shown it is also journaled intern'lediate the fureated members 36 and 37 of the bracket and above the mile-printing wheel, so as to contact therewith, whereby it rotates on the rotation of the printing-wheel, which latter is turned one thirty-second part of a rotation at each vibration of the bracket or arm 30, and for this purpose suitable ratchet mechanism is provided, shown comprising a ratchet-wheel 39, iixedly secured to the mile-printing wheel and jonrnaled for rotation therewith on said mileprinting-Wheel. shaft. To operate this ratchetwheel 39, a pawl 40 is supported in position by one member, as 3G, of the bracket 30. In the present instance this pawl is provided with a contact-face 41 and is located in position so as to engage the inner side of the top wall c of the casing, it being provided with a slot 42 therein, working on a projection 48, carried by the arm 36 of said bracket, whereby the bracket is free to move upwardly independently of said pawl 40. This pawl is maintained in operative engagement with the teeth of the ratchet-wheel 39 b v a spring 44, one end of which is connected with the upper portion of such pawl, while the opposite end thereofl acts as a detent to prevent reverse motion of the ratchet-wheel, and for this purpose such spring is maintained in position in a slotted member 45 by means of a screw 46, said slotted member 45 being carried by the member 36 of the bracket 30.

From the foregoing it will be seen that in the present improvement each time the rockshaft is actuated the record-impression arm or bracket will be vibrated thereby to carry the impression or mile-printing wheel into printing engagement with the record-sheet, such wheel being shifted one tooth each time such arm is vibrated, which shifting movement, however, takes place after the im pression on the sheet and when the printing-wheelcarrying end of the bracket moves upwardly to carry said wheel away from the recordsheet. This movement of the bracket carries the ratchet-wheel 39 into such position relatively to its pawl, the upper part of which is in engagement with the casing-wall, that said pawl operates to shift the ratchet-wheel, and thereby the mile-printing wheel, one tooth.

Since in the present instance the recordsheetis twelve inches in length and the drum carrying the same makes one rotation in an hour and the mile-printing wheel is provided with thirty-two marking or printing surfaces, it follows that when the vehicle is moving` at a speed of twelve miles an hour one inch of record-spaceis provided on the drum for each mile, so that the impression or mile-printing wheel at this speed will mark divisions one thirty-second of an inch apart, or at a speed Of twenty-four miles an hou r one sixty-fourth of an inch apart, as hereinbefore set fertili. The actuating mechanism for thisimpressionwheel bracket comprises a lever 50, secured tothe rock-shaft 3l and provided with a hardmetal shoe 51, maintained in engagement with a ratchet-wheel 52 by means of a spring 53, secured in position and shown fixed to one of the upright brackets, as This ratchetwheel 52, which maybe designated herein as a mile-wheel, since it makes one complete rotation to each mile, is provided with the same number of teeth as the mile-impression wheel 33, and therefore in the present instance it has thirty-two teeth and is shown herein secured to the hub 54 of a sixty-tooth worm-wheel 55, journaled in the present instance on a sleeve 5b' of a depending bracket 57, formed as a part of a casting B, hereinafter referred to. This worm-wheel 55 is in mesh with a single-thread worm 58, journaled within a sleeve or casing 59, likewise formed as a part of said casting B, it being cut away to permit the proper meshing of such worm and worin-wheel. In the present instance this worm-actuated ratchet-wheel 52 is operated from a rotary part-as, for instance, from the wheel of a vehicle. In the ease ofa road-vehicle this motion may be taken from any Wheel; but in the case of a street-railway car it is preferable that this motion should not be obtained from a driving-wheel, since a driving-wheel may slip and so turn without advancing the car. This ratchet-wheel 52, with its thirtytwo teeth, must make one complete rotation or turn for each mile of vehicle travel. This is accomplished in the present organization by means of suitable transmitting mechanism (see Fig. 6) shown mounted on the above-mentioned casting B, which is secured to the outer side of one end of the recorder-casing. Part of this casting B extends interiorly of the recorder-case and forms the support and casing 59 for the worm jonrnaled therein and also carries the bracket 57 for the worm-wheel All of the parts supported by this casting may be assembled therewith before it is mounted on the casing, this being permitted by providing the casing-wall with an opening e, (see particularly Fig. 6,) communicating with and extending below the cover-opening f, whereby the casting B and its assembled mechanisms may be inserted through such cover-opening and secured in position in the manner set forth, the casting having a wallsection g, adapted to cover such opening e.

This transmitting mechanism is in practice in operative connection with a rotary member-as, for instance, the wheel of a vehicle or axle thereof-which part may be provided with a cam adapted to operate a connector or rod 60, the opposite end of which is in connection with a double-stroke bell-crank 6l. In the form of connection shown (see Figs. 6 and 23) this rod 60 projects into a split sleeve 62 and is furnished with an annular groove 63, the sleeve being provided with an enlarged portion 64, having a depending bolt-carrying portion 65 for the reception of a bolt 66, which registers with the groove 63 of said rod, and thereby maintains the sleeve and rod in firm connection with each other. The upper part of this sleeve is provided with a threaded cap 67 to form an oilchamber 68 for the recept-ion of suitable oilfeeding material. The bellcran k 6l is loosely mounted upon the hub of a ratchet 69, hereinafterdescribed, and has one arm 6l' thereof bifurcated to receive the enlarged portion 6e of the sleeve 62, to which it is bolted, the opposite arm 6ll thereof carrying a pawl 70, maintained in. engagement with the ratchet 69 by a suitable spring 7l, carried by said bell-crank. This ratchet 69 is journaled on a bolt carried by the casting B and is provided with twelve teeth. it being actuated one tooth for each complete double stroke of the bell-crank. Asuitable ratchet detent or pawl 72 is bolted to the casting, being maintained in working position by a spring 73, secured to said casting, and effective to prevent the reverse motion of such ratchet 69 on the working of the bell-crank. This bellcrank ratchet 69 actuates, by suitable intermediate gearing, the single-thread worm 58, and thereby the sixty-tooth worm-wheel 55, to rotate the worm-Wheel ratchet 52, the passage of each tooth ot' which actuates the shoe ofthe depending lever 50, secured to the rocksha'ft 3l, vibrates the mile-printing-wheel arm or bracket, and thereby the mile-printing wheel, to print its mark or symbol ou the record-sheet. Bythe provision otgearmechanism having the number of teeth just described it gives the thirty-two-tooth ratchet-wheel 52 one turn to seven hundred and twenty turns ot' the driving-wheel, which is substantially correct for a twenty-eight-inch driving-wheel. It is necessary that this thirty-two-tooth ratchet-wheel 52 should make, as nearly as possible, exactly one turn for each mile of vehicle travel, no matter what the diameter of the driving-wheel may be. The diameters of the wheels of streetrailway cars, automobiles, and horse-drawn carriages Vary from twenty-four inches in diameter upward, and therefore to give the thirty-two-tooth ratchetwheel 52 the correct number of rotations for a. driver of any diameter-as, for instance, between twenty-four and forty-eight inchesa twenty-eight-inch-tooth driving-gear 73/ is secured to the outer end of the single-thread worm 5S, and to which gear 73' motion is imparted from the twelve tooth bellcrank ratchet 69 by means of a pairof gears 74 and 75, one, as 74, rigid with, but removable from, the hub ol the ratchet 69, and the other, as 75, adjustably supported on the casting B, constituting an intermediate gear between such ratchet-gear 74 and said twenty-eighttooth gear '73. 'lhis gear 75 is secured to a sector-shaped arm 76, pivotally secured to said casting B, and provided with a slot 77, workingon a bolt 7S, secured to said casting, whereby this intermediate gear can mesh with variable gears having any number ot' teeth from twentyfour to forty-eight whichA it may be desired to mount upon thel twelvetooth ratchet-hub to be driven thereby.

The assemblage of the twelve-tooth ratchet 69 and the twenWeight-tooth worm drivinggear 73', together with the sixty-tooth wormwheel 55, constitute an inch ot' driving-wheel diameter, so that the introduction of a diffen ent gear on the hub ot the ratchet 69, this gear having the same number of teeth that there are inches in diameter of the selected wheel of the vehicle will cause the thirty-twotooth ratchet-wheel 52 to make one rotation to the mile ol' vehicle travel, regardless of what the selected wheel diameter may be.

In practice a ratchet-driven gear 74;, having` the desired number of teeth, may be fixed in place by the selling` agent of the recorder for use when the same is supplied to the particular vehicle in connection with which it is to operate, such selling agent carrying in stock a complete assortment ot changeable gears varying from each other by one tooth only, so that a change-gear suitable for any diameter of vehicle-wheel which it may be necessary to accommodate can be readily supplied, and to apply such change-gear to the twelvetootl1.rat'.chethub it is merely necessary to slacken the bolt which projects through the slot 77 of the sector-arm 76, [ix the selected gear in position, then move the sector-arm 76, with its intermediate pinion 75, until it meshes correctly with such ratchetgear 74 and the twenty-eight-tooth worm drivinggear 78, and then secure such sector-arm in position by its bolt.

Supported by the casting B in the interior of the recorder-case A is a suitable buffer SO (see Fig. 2 for the depending rock-shal't lever 50. In the form shown this buffer is spring-actuated and comprises a lnit'fer-head Sl, having a stem 82, encircled by a spring S3, located in a casing 8l, formed as a part of said casting, and which spring engages at one end the wall of such casing and at its opposite end the inner face of such buffer-head. This but'fer-head Sl is furnished with a recess Sl at one side, having au inclined face or wall Si". Cooperating with this inclined face S1" is an adjusting member S5, likewise having an inclined tace S5 and guided by a part of suoli casting, the adjustment of such member being obtained by a suitable screw S6. By this construction the movement of the llO buffer is limited, while also it is adjustable to take up wear. The buffer acts to raise the impression or mile-printing wheel from the record-sheet immediately after an impression has been made, and for this purpose it contacts with a member formed or secured to the lever 50.

In operation each tooth of the ratchetwheel 52 acts in the nature of a cam-surface, so that as each tooth comes into engagement withthe shoe 5l of the depending lever 50 it acts to shift said lever against its spring 53, and thereby move the rock-shaft 3l, and consequently the mile-printing wheel, away from the record-sheet until such cam-surface passes out of engagement with such shoe, whereupon the spring 53 instantly forces the depending lever into the succeeding cam recess or space, and thereby sufficiently vibrates the mileprintingwheel arm to force the printing-wheel 33 into engagement with the record-sheet to make an instantaneous impression on such sheet, this being permitted by the buffer which at this time receives the blow of such lever.

In some organizations of the present improvement the record-sheet may be so formed and supported that the shifting of the impression mechanism, and thereby the mileprinting wheel, laterally or transversely of such sheet may not be necessary, while in other forms thereofI the record-sheet may be shifted, together with its drum, laterally or transversely of the impression mechanism, which may be iiXed against lateral movement; but in the present organization, since it is more convenient to shift that mechanism which is of the least width, the impression mechanism is shown as shiftable laterally or transversely of the record-sheet simultaneously with the rotation of the sheet-carrying drum, whereby the necessity of shifting the impression mechanism at the end of each complete rotation of the record-sheet-carrying drum is avoided. Of course should it be found desirable to shift the impression mechanism laterally only at the end of each complete rotation of the drum it would not be necessary to provide the record-sheet with a helical path. Since in the present instance the impression mechanism is shifted laterally, so as to maintain the mile-printing wheel in a helical path throughout the entire width ofthe record-sheet, suitable mechanism for this purpose is provided, which in the present improvement (see Figs. 3, 4C, and 5) comprises a single-turn screw-cam 90, the hub of which is journaled on a shaft or bolt 91, carried by a suitable bracket C, secured to one, as the rear wall of the casing, and which cam is provided with a worm-wheel 92, (shown havingforty-eight teeth and designated herein as a day-wheel,) since by the means about to be described it rotates the cam completely once in twenty-four hours. This day-Wheel 92 is operated by the time mechanism and for this purpose is in connection with the minutehand post of the timepiece. The minutehand post 13 is shown extended, so as to project at the rear side of the tin'lepiece-case, and is provided with a miter-gear 93, shown provided with twelve teeth, meshing with which is a similar miter-gear 94C, mounted on a shaft 05, carrying a double-thread worm 96, in mesh with the forty-eight-tooth wormwheel 02, said worm being` mounted in a suitable casing forming part of the bracket C. Carried by the mile-printing-wheel arm or bracket 30 is a cam-engaging member 97, having an inclined face maintained in contact with the edge of the cam 90 by a suitable spring, hereinafter described. By this organization the screw-cam OO is given in the present instance a single turn in twenty-four hours, whereby the printing-wheel will be shifted across the three-inch-width recordsheet once in each twenty-four hours. At the end of the twenty-four hours, the mileprinting wheel having made a complete record for that period on the record-sheet, it is shifted back into its starting position, this being accomplished by forming the cam 90 with a straight surface or edge 90', located in parallelism with the axis of such cani, whereby when the cam has made a complete turn the cam-engaging member 97 is free of the cam-edge 90", so that the mile-wheel arm or bracket may be shifted into its starting position by means provided for the purpose, which in the present instance comprises spring-actuated means in the form of a lever 9S, pivoted adjacent to the lower wall d of the casing and in the present instance to a cross member 32", connecting the uprights or standards 32 and 32', carrying the rock-shaft 3l. The upper end of this lever 98 is provided with a friction-roll 9S', in permanent engagement with the arm or bracket 30. A spring 99 has one end thereof secured to an arm 9S, projecting from the lower end of said lever 9S, and its opposite end to a projection 32', formed on the upright or standard 32', such spring being maintained in position by a pair of projections or guides 100 and 100', one at each side edge of such spring. By this construction the arm or bracket 30 is constantly under spring tension, so that when the curved edge 90" of the cam 90 has shifted vsuch mile printingwheel arm or bracket completely across the record-sheet and is no longer effective to shift such arm or bracket the sprin g-actu ated lever instantly returns such arm to its starting position.

It will be understood, of course, that the day-wheel 92 may have any desired number of teeth and that the organization may be such that the cam 90 will shift the mile-printing-wheel arm or bracket 30 transversely of the record sheet during a period only of twelve hours instead of forty-eight hours, if desired, and that the arm or bracket 30 may be shifted in various other ways and may be engaged and released from the cam in a great number of different ways, if desired.
